Reinitialisation after
reconnection
After any reconnection of the battery,
switch on the ignition and wait at least
one minute before starting, to allow
time for the initialisation of the electron-
ic systems.
By referring to the corresponding sec-
tions, you should set or initialise the fol-
lowing systems yourself:
- one-touch electric windows,
- time and date,
- audio and navigation system set-
tings.
Check that no alert message or warn-
ing lamp comes on after switching on
the ignition.
However, if minor problems persist af-
ter carrying out these operations, con-
tact a CITROËN dealer or a qualifi ed
workshop.
